Four activity participation variables (clubs, sports, church, and parties); two indices of "risk-taking" (preference for risk-taking, getting into trouble at school); three demographic variables (sex, ethnic group, socioeconomic status); and two drug use variables (trial of cigarettes and alcohol) were examined as correlates and prospective predictors of trial of smokeless tobacco in two cohorts of seventh graders in urban Los Angeles. The data were analyzed separately for males and females. Cross-sectional logistic regression analyses indicated that correlates of trying smokeless tobacco among the seventh-grade cohorts or among these same cohorts in the eighth grade (considering those persons who had not tried smokeless tobacco in seventh grade) generally included being white, trying cigarettes, risk-taking, and attending parties. Prospective logistic regression analyses with data from subjects who had not tried smokeless tobacco in the seventh grade indicated that predictors of subsequent trial of it generally included only being white and having tried cigarettes. Sports participation predicted onset only in one cohort of female subjects but not in males. Some activities that have been proposed as being predictive of smokeless tobacco use (e.g., sports participation) are generally irrelevant for a large sample of young adolescents in urban Los Angeles. White male cigarette smokers, regardless of the activities they have engaged in, are most likely to try smokeless tobacco.
在洛杉矶市区的两组七年级学生中，研究了四个活动参与变量（俱乐部、体育活动、教会和聚会）；两个“冒险”指标（冒险偏好、在学校惹麻烦）；三个人口统计学变量（性别、种族、社会经济地位）；以及两个药物使用变量（尝试吸烟和饮酒），作为无烟烟草尝试的相关因素和前瞻性预测指标。数据按男性和女性分别进行分析。横断面逻辑回归分析表明，七年级队列或八年级同一队列（考虑那些七年级未尝试无烟烟草的人）中尝试无烟烟草的相关因素通常包括白人身份、尝试吸烟、冒险和参加聚会。对七年级未尝试无烟烟草的受试者的数据进行的前瞻性逻辑回归分析表明，随后尝试无烟烟草的预测因素通常仅包括白人身份和尝试过吸烟。体育活动参与仅在一组女性受试者中预测了开始使用，但在男性中未预测到。一些被认为可预测无烟烟草使用的活动（如体育活动参与），对于洛杉矶市区大量青少年样本通常无关紧要。白人男性吸烟者，无论他们参与何种活动，最有可能尝试无烟烟草。
